The Wizards of Waverly Place star performed a private concert benefiting UNICEF and she busted out Justin Timberlake's "Cry Me a River' — the infamous song he wrote after his split with Britney Spears.

Without mentioning her ex, Selena told the crowd, "I've been through a lot the past few months. It's been weird and sad and cool."

According to Radaronline.com the two spent New Year's apart and have realized they've been trying to make something work that isn't meant to be right now.

"Justin and Selena were together for a long time. They love each other and will always care about each other, but it just isn't working between them," a source said.

The pair broke up in November, then briefly got back together a few weeks later and went on vacation in Utah over the Christmas holiday, but have since ended their relationship.

"This might really be it for the two of them. They're over going back and forth and all the fighting and reconciling. They're finally realizing that no matter how much they try to make it work, it won't right now," the source added.
